US Classification:

362547, 362511, 362496, 362498, 29619309, 2961931

Abstract:

A body panel for a vehicle includes an outer lens and a light engine projecting a light into the outer lens. The body panel includes a duct, which is disposed at a substantially equal vertical elevation as the outer lens. The light engine is positioned relative to the outer lens to allow the duct to pass directly behind the outer lens, at approximately the same vertical elevation, to improve air flow through the duct.

International Classification:

F21S 45/60
F21S 45/50
F21S 41/20
H05B 3/84

Abstract:

A lamp assembly includes a housing forming an interior space, and having a first portion and a second portion. A light source is disposed within the interior space and positioned to direct light through the first portion. An electrically resistive coating is disposed on the first portion of the housing, and is operable to heat the first portion to create a positive temperature gradient in which the first portion exhibits a higher temperature than the second portion so that moisture within the interior space condenses on the second portion and not the first portion. A self-contained power supply, including an energy storage device and a solar cell, may be incorporated into the housing. An interior surface of the first portion may be coated with a hydrophobic coating, and an interior surface of the second portion may be coated with a hydrophilic coating.

Inventors:

- Detroit MI, US
Mark Roscoe - Shelby Township MI, US
Mark R. Gordon - Warren MI, US

International Classification:

F16C 11/06

US Classification:

403 76, 2989807

Abstract:

An assembly for enabling multi-adjustment of a lamp is provided. The assembly includes a frame to which the lamp is attachable, a ball joint, and an apparatus for retaining the ball joint. The ball joint has a head and a neck. The apparatus is attached to the frame, and includes a housing and a cap. The housing defines a chamber configured to receive the head of the ball joint. The housing may further define a slot in which the neck is slidable such that the ball joint is insertable into and removable from the chamber. The cap is configured to interlock with the housing to secure the ball joint such that they are substantially restricted to rotational movement with respect to each other. The cap and the housing may have retention tabs and retention ridges, respectively, configured to engage with each other to enable the interlocking.
